The Custom Building Product RedGard Membrane is a premium underlayment solution designed to provide superior protection for ceramic, porcelain, natural stone, and other installations. This infloor underlay membrane is specially formulated to help prevent cracks in shower floor tile and grout. One of the standout features of the RedGard Membrane is its cost-efficiency. With just a single 1/8" thick roll, you can replace 3-4 sheets of 1/4" backerboard (6mm underlayment). It is used with polymer-modified thin-set mortar adhesive, which is recommended for bonding porcelain and difficult-to-bond flooring tiles. This membrane forms a strong bond thanks to its reinforced fleece bonding layer. No fasteners are required for the installation, simplifying the process and saving time. Additionally, the mat itself is made from 70% recycled materials, showcasing its commitment to sustainability. The RedGard Isolation Membrane functions as both a waterproof and vapor-proof uncoupling membrane for tile. This makes it suitable for crack prevention in porcelain, glass tiles, mosaic, natural stone, concrete blocks, linoleum, and carpet tiles. In case of excessive substrate movement, it effectively absorbs stress, preserving the surface and integrity of the ceramic floor tile. It is easy to install and compatible with different tile types offering superior protection and stability for your waterproof flooring projects. Whether used in standard applications or over challenging substrates, the in-floor RedGard Membrane ensures the longevity and performance of your tile installations. RedGard tile membrane underlayment can also be used when renovating older kitchen tile flooring, basement flooring, and bathroom floor tile. This includes DIY home improvement projects too. RedGard addresses the existing in-plane cracks in the bathroom flooring tile subfloor and prevents lateral stresses from being transferred to stone tiles flooring and other floor underlayment types.
